     I am pretty sure I have an M92652 (4D)-Ser#0720156 scanner that has stopped working.  The display has range rings and all the peripheral data but no returns are present.  It is connected to an RL70C Plus Pathfinder display (E52033)-Ser#0720165.  Rather than getting my old scanner repaired, or buying a used scanner, I am more interested in getting a new scanner that is compatible with my current display system.  My questions would be;1)  Are the RD218 or RD424 scanners compatible with the RL70C Plus Pathfinder display?2)  If yes, can I use my current "4 core" cable with a RD218 scanner by simply using only 2 of the lines (1 red and 1 black)?  I don't want to spend the extra $600 to get the added range that I never use.      Thanks,  TomSee More
